The site pairs dueling live-streams of instrumental ambient music culled from Soundcloud with chatter taken from the LAPD Citywide Dispatch and Hot Spots radio frequency. It's a simple idea, but the tandem streams make you feel as if you're starring in your own private "Collateral" or "Drive."

Most of the time, the radio signals just lend a general air of haunted noir to the music, which seems to come largely from home producers. But when something recognizable sticks out, such as a call about an incident at 8th Street and Broadway Avenue in downtown L.A., it makes the uneasy feelings hit home.
